Introduction to Ultrasonic Time-of-Flight Measurement & the Prosonic M FMU40

1. Ultrasonic Time-of-Flight (ToF) Measurement

Ultrasonic ToF measurement works by emitting sound pulses—typically ultrasonic—towards a target surface. The sensor then measures the time it takes for the echo to return. Since the speed of sound in the medium (e.g., air) is known, this time interval can be converted into a distance measurement, enabling accurate, non-contact detection of levels in tanks, silos, channels, and more.

2. Prosonic M FMU40 Overview

The Prosonic M FMU40 by Endress+Hauser is a rugged, compact ultrasonic sensor designed for continuous, non-contact level and flow measurement using the ToF principle.

Core Capabilities & Applications:

  • Measures levels in liquids, pastes, and coarse bulk materials (e.g., powders or pellets).
  • Can also monitor flow in open channels or at weirs, making it versatile across applications
  • Suited for installations on storage tanks, agitators, stockpiles, and conveyor belts

3. Key Features & Specs

Feature

Details

Mounting & Design

Compact two-wire or four-wire transmitter; threaded process connection; PVDF sensor part for chemical resistance

Measurement Range

Up to 5 m for liquids; 2 m for solids; maintains accuracy within ±2 mm or ±0.2% of range

Environmental Resistance

Operating temperature: –40 °C to +80 °C (–40 °F to +176 °F)
Pressure range: 0.7 to 3 bar abs. (≈ 10 to 44 psi)

Built-In Temperature Compensation

Integrated temperature sensor automatically corrects for variations in sound velocity due to temperature changes

Display & Diagnostics

Menu-guided, four-line plain text display (selectable in 7 languages); can show envelope curves for real-time echo validation and diagnostics

Linearization Function

Supports up to 32-point linearization to convert distance readings into meaningful units—such as volume, flow rate or length

Robust Build & Safety

Hermetically sealed and potted sensor housing; complies with international explosion protection standards (e.g. ATEX)

Calibration

Can be performed without filling or draining the vessel—simplifying maintenance and reducing downtime

4. Typical Use Cases

  • Liquid level control in water treatment tanks, chemical storage, etc.
  • Flow monitoring in open channels or spillways (e.g. weirs).
  • Bulk solids measurement for items like pellets, grains, or powders stored in silos.
  • Process control environments involving dynamic or difficult-to-access systems—like agitators or conveyor systems.

Summary

The Prosonic M FMU40 is a reliable ultrasonic level sensor offering:

  • Non-contact measurement, ensuring longevity and minimal maintenance.
  • Versatility across liquids, solids, and flow applications.
  • User-friendly display and diagnostics, aiding quick commissioning and troubleshooting.
  • Precise and customizable output, thanks to accurate ranging and linearization.
  • Robust design and safety, suitable for industrial and potentially hazardous environments.
